Re: no links work at all (noob)
The only problems are ‘news’, ‘members’, ‘groups’ buttons in the home theme? All else works ok? I don’t know what blog.php has to do with anything. If you hit ‘news’ bp uses ‘index.php’ to display latest posts on that blog.
If members and groups directories aren’t running at all then you should be getting an error msg.. ok stop..
I re-read your msg and you are getting 404s but things are running. Ok. It helps to actually read the other person’s msg. (sigh)
The 404’s are a known problem when running the various directories. A workaround to eliminate the 404s is to create pages with the same slug as the directory slugs.
members
groups
blogs
Three pages with the above slugs should eliminate the 404s. They just serve as placeholders.
